Health systems research, evidence-informed decision making

Faglig bakgrunn

Simon is a Senior Researcher at the Norwegian Institute of Public Health and a Chief Specialist Scientist at the South African Medical Research Council. Having trained in South Africa and the UK, I have worked for over 20 years in the field of health policy and systems research. I have a keen interest in how research evidence can be used to inform decisions for health systems in low- and middle-income countries (LMICs) and at the global level in multilateral organisations such as the WHO, and have worked closely with WHO on guideline development methods. My methodological interests include approaches for undertaking systematic reviews of complex health system interventions, and methods for synthesizing the findings of multiple qualitative studies and assessing confidence in such findings. Together with colleagues at the Norwegian Institute of Public Health, I coordinated a recent landmark series of papers on the GRADE-CERQual approach for assessing confidence in findings from systematic reviews of qualitative studies. I am currently exploring how qualitative evidence can contribute to humanizing health decision making through highlighting the perspectives of key stakeholders, including marginalized groups – this work was highlighted in the recent Global Symposium on using qualitative evidence to inform decisions in the SDG era which we organized together with the Oswaldo Cruz Foundation in Brasilia. As Joint Co-ordinating Editor of Cochrane Effective Practice and Organisation of Care (EPOC) and lead for the Norwegian EPOC satellite, I have played a key role in strengthening Cochrane’s work in the field of health systems and in developing Cochrane methods for qualitative evidence synthesis. I work with partners in Brazil, Chile, Colombia, South Africa and Uganda and with the wide EPOC LMIC network. I am also currently an Honorary Professor in the Faculty of Public Health and Policy at the London School of Hygiene and Tropical Medicine, Chair of the Governance Group o
